Abstract
The flame characteristics of turbulent premixed jet flames fuelled with stoichiometric hydrogen/methane mixtures are studied using Direct Numerical Simulation (DNS). The study investigates four cases with 0, 10, 50, and 80% hydrogen by volume while maintaining the jet Reynolds number at 10,300. The addition of hydrogen leads to reduced wrinkling as the flame moves from the thin-reaction zone regime towards the corrugated flamelet regime. This study underlines the importance of using appropriate non-dimensionalisation parameters for generalising the findings. Specifically, the flame thickness defined by Peters (2000) which use the conditions at the point of the maximum heat release rate is fo..
